What is the coolest online forum, one where scientists and great minds from all over the world exchange opinions and ideas, and the one that keeps the scientific debate alive? Almost certainly it’s edge.org, an American website whose most ardent supporters include, to quote some of the best known, Richard Dawkins, the famous and controversial evolutionary biologist and author of The Selfish Gene; Brian Eno, the visionary music producer; psychologist Steven Pinker; and physicists like Alan Guth or Gino Segré, who are changing the present vision of the universe. This where you’ll run into debates that count, thanks also to a device that has started a cultural trend: every year edge.org asks an artful question that the big brains who haunt its electronic pages are invited to answer. This year’s question is: What have you changed your mind about? Why?
The mea culpa flocked in in great numbers and from prestigious sources, (more than a hundred in a few days), revealing that the greatest minds are changing their opinions on a lot of subjects, from the expansion of the universe to evolution, from the meaning of science to the workings of the human brain through the value of the Roman Empire in front of the barbarians.
